Question

我有工作清单。我必须通过使用axios将'jobid'作为参数传递来检索工作详细信息。我为此创建了动作和减速器并连接到该组件。 api被调用，但在jobid中显示未定义。我认为这是路线问题。请建议我在哪里定义以及如何获取详细信息。

我的api很像（例如：“ http://localhost:3000/app/jobs/87938”）。这里的jobid是87938。我的工作清单中有多个工作，每个工作的id不同。问题是如何定义Jobid并将其传递给api以获取作业的详细信息

操作代码：

export const retrieveLocations = (jobId) => (dispatch) => {
  axios.get(retrieveUrl+'/jobs/'+jobId).then(res => {
      dispatch({
          type: RETRIEVE_LOCATION,
          payload: res.data.job.basicDetails
      });
  });
};

减速器代码：

case 'RETRIEVE_LOCATION':
            return{
                ...state,
                conLocations:action.payload
            }

组件代码：

class ConfiguredLocation extends React.Component{
    constructor(props){
        super(props);

        this.handleRemove = this.handleRemove.bind(this);
        this.clearall = this.clearall.bind(this);
    }


    handleRemove(mruCode){
       this.props.removeLocation(mruCode)
    }

    clearall (){
      this.props.removeAllLocation()
    }
    componentDidUpdate(prevProps){
        let currJobId = this.props.match.params.jobId;
        let prevJobId = prevProps.match.params.jobId;
        if(currJobId!==prevJobId){
            this.props.retrieveLocations(jobId);
        }
    }
    componentDidMount(){
        let {jobId} = this.props.match.params;
        this.props.retrieveLocations(jobId);
    }

    render(){
        const _labels = store.getLabels();
        const {conLocations} = this.props;
        return(
            <div className="col-padding">
              <div className="pos-div"><h3>Configured Location</h3><button className="allLargeBtn" onClick={()=>{this.clearall()}}>Remove all location</button></div><hr/>
               <table className="table">
                    <tbody>
                        {conLocations.map((loct,index)=><tr key={index}>
                           <td><h5>{loct.mruCode} - {_labels[loct.division]} - {loct.country}</h5></td>
                           <td className="text-right"><img alt="DeleteIcon" onClick={()=>this.handleRemove(loct.mruCode)}className="deleteIconStyle" src="img/delete_large_active.png" /></td>
                        </tr>
                        )}
                    </tbody>
               </table>
            </div>
        );
    }

}

const mapStateToProps = state =>{
    return {
        conLocations: state.locationRed.conLocations
    };
  };

  const mapDispatchToProps = (dispatch) =>{
      return{
          removeLocation: (mruCode)=>{dispatch(removeLocation(mruCode))},
          removeAllLocation: () =>{dispatch(removeAllLocation())},
          retrieveLocations:(jobId) =>{dispatch(retrieveLocations(jobId))}
      };
  };


export default connect(mapStateToProps,mapDispatchToProps)(withRouter(ConfiguredLocation));

路由器代码（应用导航器-我无法在此处定义作业ID。请在此建议我）

import React from 'react';
import ReactDOM from 'react-dom';
import {Router, Route} from 'react-router-dom';
import { Security, ImplicitCallback, SecureRoute } from '@okta/okta-react';
import history from '../history';
import store from '../stores/store';
import ConfiguredLocation from '../components/location/ConfiguredLocation';
class AppNavigator extends React.Component {

    constructor( props ) {
        super( props );
        this.state = {
            loading: true
        };
    }

    componentDidMount() {
        var self = this;
        setTimeout(() => {
            self.setState({ loading: false });
        }, 1000);
    }

    render() {
        if (this.state.loading) {
            return (
                <div className="fix"><i className="fa fa-2x fa-circle fa-spin"></i>
                    <div>Loading</div>
                </div>
            )
        } else {
            return (                    
                <Router history={history}>
                    <Security issuer={Something..}
                        client_id={something...}
                        redirect_uri={window.location.origin + '/app/callback'}
                        scope={['profile', 'openid']}>
                        <Route path='/callback' component={ImplicitCallback} />
                        <AppFrame />
                    </Security>
                 <Route exact path= '/jobs/:jobId' component={ConfiguredLocation}
                </Router>
            );
        }
    }
};

商店代码：（调用了导航程序的地方）

<Provider store={createStoreWithMiddleware(reducers)}>
            <AppNavigator />
        </Provider>

一切正常。如果我不带参数调用api。它工作正常。因此，我无法正确路由参数。请帮助我。

所有代码在编辑后都是正确的。当您要生成动态路由时，例如jobId中的/app/jobs/87938，首先应将此路由写入路由器文件中，如下所示：

<Route exact path="/app/jobs/:jobId" component={ConfiguredLocation}/>

之后，在打开http://localhost:3000/app/jobs/87938时，您的jobId为87938，您可以在componentDidMount生命周期中获取它：

componentDidMount() {
    const {jobId} = this.props.match.params;
    this.props.retrieveLocations(jobId);
}
